IDE, not SATA, right? Just so we have the terms straight, let me explain: IDE = 40/80 pin ribbon cable, connects motherboard to disk and CD/DVD drives SATA = 4 pin twisted serial cable. Connects motherboard to disk and CD/DVD drives ATA = Command language spoken by _hard_drives_ that are connected via IDE or SATA ATAPI = Command language, similar to SCSI, that is spoken by CD/DVD drives over IDE and SATA There is no such a thing as an ATA DVD drive, but there are ATAPI DVD drives. The interesting question is whether yours is IDE or SATA.
